If this happens, there is something (C) affixed preventing the
tooth (1) from fitting completely in adapter (4). Locate the
problem and remove the obstruction. When tooth (1) fits
completely in adapter (4), knock in lock pin (2).
9. Insert lock pin (2) in the pin hole in tooth (1), and knock it in
so that the top surface of lock pin (2) is the same height as
the surface of tooth (1).
10. After replacing a bucket tooth, always check the following.
1) After lock pin (2) is knocked in completely, check that it
is secured by teeth (1) and surface.
2) Lightly hit lock pin (2) in the reverse direction from which
it was hit in.
3) Lightly hit the tip of teeth (1) from above and below, and
hit its sides from right and left.
4) Confirm that rubber pin lock (6) and lock pin (2) are set
as shown in the right figure.
REMARK
If the tooth is turned, the wear will become uniform. This will extend the service life of the tooth and reduce the fre-
quency of replacement.
When replacing the tooth, replace the rubber pin lock and lock pin with new parts at the same time. This will pre-
vent the tooth from falling out.
